【発明の属する技術分野】
本発明は、ICカードや通信カード等のカードと接続されるカードコネクタに関し、特に、カードの飛び出しを防止するロック機構を備えたカードコネクタに関する。
【0002】
【従来の技術】
通常、カードコネクタはカードを排出させるイジェクト機構を備えている。イジェクト機構の一つとしてW−PUSH式又はプッシュプッシュ式と呼ばれるものが知られている。この種のイジェクト機構は、挿入されたカードとともにコネクタ内を移動するイジェクトレバーを有している。
【0003】
カードコネクタからのカードの飛び出しを防止するロック機構の一部品であるロック部材をイジェクトレバーに保持させることが提案されている(例えば、特許文献1参照)。特許文献1では、ロック部材はイジェクトレバーに片持ち梁状に圧入保持され、そのロック部材の弾性変形により、ロックのための係止爪を移動させてカードのロック若しくはそのロックの解除を行う。
【0004】
また、ロック機構がロック部材を回転軸を中心として回転可能に備えたものもある(例えば、特許文献2及び特許文献3参照)。

特開2001−203034号公報
【0008】
【発明が解決しようとする課題】
最近のカードコネクタには小型化が要求され、必然的にイジェクトレバーにも小型化が要求される。極限まで小型化されたイジェクトレバーはロック部材の変形時のモーメントを十分な剛性で保持するには不利である。特に、特許文献1のようにロック部材をイジェクトレバーに片持ち梁状に圧入保持させたものでは、実用上では強度的に無理がある。
【0009】
それ故に本発明の課題は、イジェクトレバーが小型化しても耐久性に富むロック機構を備えたカードコネクタを提供することにある。
【0010】
【課題を解決するための手段】
本発明によれば、カードの接続に使用されるカードコネクタであって、カード受け入れ領域を規定する筐体と、前記筐体にスライド自在に保持され、前記カード受け入れ領域から前記カードを排出するイジェクトレバーと、前記イジェクトレバーに揺動可能に保持されたロック部材とを備え、前記筐体はカム部を有し、前記ロック部材は、前記カム部に係合するカムフォロワー部と、前記カードの離脱を係止する係止部とを有し、前記イジェクトレバーをスライドさせることにより、前記カム部と前記カムフォロワー部とが協働して、前記係止部による前記カードの係止及び該係止の解除を行うようにしたことを特徴とするカードコネクタが得られる。
【0011】
前記筐体は、ベースと、該ベースに固定されたカバーとを有し、前記イジェクトレバーは前記ベースに保持され、前記カム部は前記カバーに形成されていてもよい。
【0012】
前記ロック部材は、底部を前記イジェクトレバーに回動可能に係合された略U字状部を有し、前記略U字状部のU字の一端に前記カムフォロワー部が設けられ、前記略U字状部のU字の他端に前記係止部が設けられていてもよい。
【0013】
前記係止部は、前記イジェクトレバーのスライドに応じかつ前記カム部の形状にしたがい前記カード受け入れ領域に出没するものでもよい。
【0014】
【発明の実施の形態】
図1−図3を参照して、本発明の実施の形態に係るカードコネクタの全体について説明する。
【0015】
図示のカードコネクタは、ICカードや通信カード等のカードと接続するものであって、カード受け入れ領域を規定する筐体1と、筐体1の一端に備えた、カードの挿入を検知するためのディテクションスイッチ2と、筐体1に第1及び第2の方向A1及びA2に往復スライド自在に保持され、カード受け入れ領域からカードを排出するイジェクトレバー3と、イジェクトレバー3に揺動可能に保持されたロック部材4とを備えている。
【0016】
筐体1は、ハウジング又はベース5と、ベース5に固定されたカバー6とを有し、これらの間にカード受け入れ領域を規定している。イジェクトレバー3はベース5に保持されている。カバー6にはスライドカム溝即ちカム部7が形成されている。カム部7は、その途中部分に、第1及び第2の方向A1及びA2に対し傾斜した部分7aを有している。
【0017】
ベース5には、筐体1のカード受け入れ領域に挿入されたカードに電気的に接続される複数の導電性のコンタクト8と、複数のホールドダウン9とが配備されている。
【0018】
図4および図5をも参照して、イジェクトレバー3及びロック部材4について説明する。
【0019】
イジェクトレバー3はスプリング(図示せず)により第1の方向A1に常時付勢されている。イジェクトレバー3にはハートカム11が形成されている。ハートカム11には、筐体1に固定のカムフォロワー(図示せず)が係合している。
【0020】
カードが筐体1の他端からカード受け入れ領域に挿入されるとき、カードに押されてイジェクトレバー3が第2の方向A2にスプリングを蓄勢しつつスライドする。所定の位置まで押し込まれると、押圧力を解除しても、ハートカム11の作用によりイジェクトレバー3は押し込まれた状態に係止される。このとき、カードはコンタクト8に電気的に接続される。
【0021】
カードをさらに少し押し込むと、ハートカム11の作用によりイジェクトレバー3の係止が解除される。したがってイジェクトレバー3はスプリングの付勢力により第1の方向A1に移動する。その際、イジェクトレバー3がカードをコンタクト8から切り離しかつカード受け入れ領域から押し出す。
【0022】
こうしてハートカム11の作用によりイジェクトレバー3はW−PUSH式のイジェクト機構として働く。この種のイジェクト機構は、特許文献1及びその他の文献に詳しく記載されているので、ここではこれ以上の説明を省略する。
【0023】
一方、ロック部材4は略U字状部12を有している。略U字状部12のU字の底部は、ベース5に固定の支軸13により、イジェクトレバー3に回動可能に係合されている。略U字状部12のU字の一端には摺動子又はカムフォロワー部14が設けられている。また、U字状部12のU字の他端には係止爪又は係止部15が設けられている。
【0024】
カムフォロワー部14はカバー6のカム部7に挿入されて係合する。したがって、イジェクトレバー3を第1及び第2の方向A1及びA2に往復スライドさせると、カム部7の形状にしたがいロック部材4は支軸13を支点として揺動する。
【0025】
係止部15は、ロック部材4の揺動にしたがい、カード受け入れ領域に出没する。コネクタ本体2に接続されているときに係止部15がカード受け入れ領域に突出すると、係止部15はカードの側縁の凹部に係合し、カードの離脱を係止する。係止部15がカード受け入れ領域から引っ込むと、係止部15によるカードの係止が解除されるため、カードを離脱させることが可能になる。
【0026】
図6(a),(b)をも参照して、このカードコネクタの実際の動作について説明する。
【0027】
カードが挿入されていない状態を示す図5(a)では、イジェクトレバー3が第1の方向A1に移動しかつ係止部15がカード受け入れ領域から引っ込んでいる。カードが挿入されると、カードに押されてイジェクトレバー3が第2の方向A2に移動する。その際に、カム部7とカムフォロワー部14とが協働してロック部材4を一方向に揺動させる。その結果、図5(b)に示すように係止部15がカード受け入れ領域に突出し、カードの凹部に係合する。この状態でカードの挿入を進行させると、カードがコンタクト8に接続される。コンタクト8に接続されているときには、カードは係止部15に係止され、不慮の離脱を阻止される。
【0028】
カードがさらに押し込まれると、上述したようにハートカム11の作用によりイジェクトレバー3の係止が解除され、スプリングの付勢力によりイジェクトレバー3が第1の方向A1に移動する。その際に、カム部7とカムフォロワー部14とが協働してロック部材4を反対方向に揺動させる。その結果、図5(a)に示すように係止部15がカード受け入れ領域から引っ込み、イジェクトレバー3の窪み16に入るため、カードの凹部との係合が解除される。したがって、カードはスムースにコンタクト8から切り離され、カード受け入れ領域から排出可能になる。
【0029】
なお、図1に示すように、カバー6に、カードを制動するための複数のカードブレーキ17、及びカバー6をホールドダウン9に接続するための複数の接続バネ18を備えることは好ましい。
【0030】
【発明の効果】
以上説明したように、本発明によれば、ロック部材をイジェクトレバーに圧入させるという構造ではないため、イジェクトレバーが小型化しても耐久性に富むロック機構を備えたカードコネクタを提供することが可能である。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a card connector connected to a card such as an IC card or a communication card, and more particularly to a card connector having a lock mechanism for preventing the card from jumping out.
[0002]
[Prior art]
Usually, the card connector has an ejection mechanism for ejecting the card. As one of the eject mechanisms, a so-called W-PUSH type or push-push type is known. This type of eject mechanism has an eject lever that moves in the connector together with the inserted card.
[0003]
It has been proposed that a lock member, which is a component of a lock mechanism for preventing a card from popping out of a card connector, is held by an eject lever (for example, see Patent Document 1). In Patent Literature 1, a lock member is press-fitted and held by an eject lever in a cantilever shape, and a locking claw for locking is moved by elastic deformation of the lock member to lock a card or release the lock.
[0004]
Further, there is a lock mechanism in which a lock member is provided so as to be rotatable about a rotation axis (for example, see Patent Literature 2 and Patent Literature 3).

Japanese Patent Application Laid-Open No. 2001-203034
[Problems to be solved by the invention]
Recent card connectors are required to be miniaturized, and inevitably the eject lever is also required to be miniaturized. The eject lever, which has been miniaturized to the limit, is disadvantageous in that the moment when the lock member is deformed is held with sufficient rigidity. In particular, in the case where the lock member is press-fitted and held in the form of a cantilever on the eject lever as in Patent Literature 1, the strength is impractical in practical use.
[0009]
Therefore, an object of the present invention is to provide a card connector provided with a lock mechanism that is highly durable even when the eject lever is downsized.
[0010]
[Means for Solving the Problems]
According to the present invention, there is provided a card connector used for connection of a card, a casing defining a card receiving area, and an ejecter slidably held by the casing and ejecting the card from the card receiving area. A lever, and a lock member swingably held by the eject lever; the housing has a cam portion; the lock member is a cam follower portion that engages with the cam portion; A locking portion for locking the detachment, and by sliding the eject lever, the cam portion and the cam follower portion cooperate with each other to lock the card by the locking portion, and A card connector characterized in that the stop is released.
[0011]
The housing may include a base and a cover fixed to the base, the eject lever may be held by the base, and the cam portion may be formed on the cover.
[0012]
The lock member has a substantially U-shaped part whose bottom is rotatably engaged with the eject lever, and the cam follower part is provided at one end of a U-shaped part of the substantially U-shaped part, and the cam follower part is provided. The locking portion may be provided at the other end of the U-shape of the U-shaped portion.
[0013]
The locking portion may be configured to protrude and retract from the card receiving area in accordance with the slide of the eject lever and according to the shape of the cam portion.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
With reference to FIG. 1 to FIG. 3, an entire card connector according to an embodiment of the present invention will be described.
[0015]
The illustrated card connector connects to a card such as an IC card or a communication card, and includes a housing 1 that defines a card receiving area, and one end of the housing 1 for detecting insertion of the card. A detection switch 2, an eject lever 3 that is slidably held in the housing 1 in reciprocating first and second directions A1 and A2, ejects the card from the card receiving area, and is swingably held by the eject lever 3. Lock member 4 provided.
[0016]
The housing 1 has a housing or base 5 and a cover 6 fixed to the base 5 and defines a card receiving area therebetween. The eject lever 3 is held by the base 5. The cover 6 has a slide cam groove or cam portion 7 formed therein. The cam portion 7 has a portion 7a at an intermediate portion thereof that is inclined with respect to the first and second directions A1 and A2.
[0017]
The base 5 has a plurality of conductive contacts 8 electrically connected to a card inserted into the card receiving area of the housing 1 and a plurality of holddowns 9.
[0018]
The eject lever 3 and the lock member 4 will be described with reference to FIGS.
[0019]
The eject lever 3 is constantly urged in a first direction A1 by a spring (not shown). A heart cam 11 is formed on the eject lever 3. A cam follower (not shown) fixed to the housing 1 is engaged with the heart cam 11.
[0020]
When the card is inserted into the card receiving area from the other end of the housing 1, the eject lever 3 is pushed by the card and slides in the second direction A2 while accumulating a spring. When the eject lever 3 is pushed to a predetermined position, the eject lever 3 is locked in the pushed state by the action of the heart cam 11 even if the pushing force is released. At this time, the card is electrically connected to the contact 8.
[0021]
When the card is further pushed in a little, the lock of the eject lever 3 is released by the action of the heart cam 11. Therefore, the eject lever 3 moves in the first direction A1 by the urging force of the spring. At that time, the eject lever 3 separates the card from the contact 8 and pushes the card out of the card receiving area.
[0022]
Thus, the eject lever 3 functions as a W-PUSH type eject mechanism by the action of the heart cam 11. Since this type of eject mechanism is described in detail in Patent Document 1 and other documents, further description is omitted here.
[0023]
On the other hand, the lock member 4 has a substantially U-shaped portion 12. The U-shaped bottom of the substantially U-shaped portion 12 is rotatably engaged with the eject lever 3 by a support shaft 13 fixed to the base 5. A slider or a cam follower portion 14 is provided at one end of the U-shape of the substantially U-shaped portion 12. A locking claw or locking portion 15 is provided at the other end of the U-shaped portion 12.
[0024]
The cam follower part 14 is inserted into and engaged with the cam part 7 of the cover 6. Therefore, when the eject lever 3 is reciprocated in the first and second directions A1 and A2, the lock member 4 swings around the support shaft 13 according to the shape of the cam portion 7.
[0025]
The locking portion 15 protrudes and retracts in the card receiving area as the locking member 4 swings. When the locking portion 15 protrudes into the card receiving area while being connected to the connector main body 2, the locking portion 15 engages with the concave portion on the side edge of the card and locks the removal of the card. When the locking portion 15 is retracted from the card receiving area, the locking of the card by the locking portion 15 is released, so that the card can be removed.
[0026]
The actual operation of the card connector will be described with reference to FIGS. 6 (a) and 6 (b).
[0027]
In FIG. 5A showing a state where a card is not inserted, the eject lever 3 moves in the first direction A1 and the locking portion 15 is retracted from the card receiving area. When the card is inserted, the eject lever 3 is pushed by the card and moves in the second direction A2. At this time, the cam 7 and the cam follower 14 cooperate to swing the lock member 4 in one direction. As a result, as shown in FIG. 5B, the locking portion 15 protrudes into the card receiving area and engages with the concave portion of the card. When the insertion of the card proceeds in this state, the card is connected to the contact 8. When the card is connected to the contact 8, the card is locked by the locking portion 15 to prevent accidental detachment.
[0028]
When the card is further pushed in, the lock of the eject lever 3 is released by the action of the heart cam 11 as described above, and the eject lever 3 moves in the first direction A1 by the biasing force of the spring. At this time, the cam 7 and the cam follower 14 cooperate to swing the lock member 4 in the opposite direction. As a result, as shown in FIG. 5A, the locking portion 15 is retracted from the card receiving area and enters the depression 16 of the eject lever 3, so that the engagement with the concave portion of the card is released. Therefore, the card is smoothly separated from the contact 8 and can be ejected from the card receiving area.
[0029]
As shown in FIG. 1, it is preferable that the cover 6 includes a plurality of card brakes 17 for braking the card and a plurality of connection springs 18 for connecting the cover 6 to the holddown 9.
[0030]
【The invention's effect】
As described above, according to the present invention, since the lock member does not have a structure in which the lock member is pressed into the eject lever, it is possible to provide a card connector having a lock mechanism that is highly durable even when the eject lever is downsized. It is.
